Major cities in Spain such as Valencia, Madrid or Barcelona suffered traffic jams because of demonstrations where trucks were driven at low speeds, making getting around difficult for other vehicles (the picture above shows one of Barcelona's main entry, the C-58 highway). The two main borders between Spain and France, La Jonquera and Irun, were also blocked and demonstrators prevented any truck from crossing. In response, the Spanish government offered an agreement to the Freight Unions. It includes a flexible fare system where transport could reflect fuel prices directly, as well as other measures like subventions for early retirement.
